"Streaming" is a real-time data processing feature in Apache Hadoop. It allows users to input data streams (such as live data feeds) into MapReduce jobs, enabling them to process large volumes of data in real time without the need for preprocessing or storage.nThe Hadoop Streaming API facilitates this by allowing users to write their custom mappers and reducers using scripts written in various programming languages such as Python, Perl, and Java.
